Classification is done with traffic desriptors Ingress interface CoS value on ISL or 802.1P frames Source/destination IP address IP Precedence or DSCP value MPLS EXP Application type Layer 3 QoS Type of Service […]
I’ll try to keep it a little shorter this time. Major issues for converged enterprise networks Available bandwidth: competition among applications Fixes Increase bandwidth: More power! Properly queue based on classification and marking: QoS Compress: cRTP, TCP header compression, etc. Delay: Lead time to get a packet to the destination Types of delay Processing delay: […]
